K-x color problem or not ??

I just ordered a "great condition" used K-x, mostly based on dpreview comments , but I ran across another site today that gave the K-x dismal scores on color rendition, even compared to other entry-level units.

Samples on PicasaWeb and Flicker don't look bad, but what about you guys and gals who have owned one - what do you say ?

PS: I see updates to the K-x on the Pentax website, but nothing about color fixes.
